Silc3r using wrong extruder

I'm testing a dual extruder printer, and most of the time everything works ok.

Often, I'll want to test just a single extruder, and I'll turn off the raft, only to find my object prints on the second extruder.

I'm not sure why this is happening, I wonder if it has to do with "extruder 1" and "extruder 0" perhaps referencing the same thing when only one extruder is used?

Any suggestions on where to look?

This will give me an object printed ENTIRELY with Extruder 2. It doesn't show up as such until I export the g-code, then the screen will update if I remember to look.

No idea how to fix it. Sometimes it works after I change a bunch of settings at random, but it seems a problem. This is a two *physical* extruder/nozzle printer with the offsets handled in firmware.

I wonder if it's related to my start up G-code, which leaves Tool2 enabled.

It might make sense to add a line to explicitly activate the right tool at the beginning of the print?

For multi-extruder models, Slic3r numbers the tools 1, 2, 3, 4, etc.

There is no extruder 0.

Try specifying extruders 1 and 2, rather than 0 and 1, and see if that works.

If you float your cursor over the blank, you'll find that 0 has a special meaning, it does NOT mean "Extruder #0".
